GLASS-CUTTER.

I Specification of Letters Patent.

Patented Dec. 2, 1909.

Application filed January 4, 1909. Serial No. 470,705.

To all whom it may concern:

Be it known that I, JAMES W. TUGKER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Glass-Cutters, of which the following is a specification.

This invention relates to glass cutters, the object being to produce a cheap, simple and efficient glass cutter, of that class which con tains oiling devices for the cutting wheel and the pin upon which it revolves. Considerable effort has been made to produce an effective tool of this class, but these devices require constant attention to maintain them in perfect working order, and they are very liable to get out of order at the time that the tool is to be used, and are usually of expensive and complicated construction.

It is my object to remedy these objectionable features by producing a ready and serviceable article.

To such ends this invention consists in a glass cutter of the ordinary and well known form, but improved by the addition of a wad of absorbent material such as felt, wool, sponge and the like, supported upon the tool in such position that it will apply oil, which has been previously absorbed by it, to the cutting wheel or disk and pin.

It further consists in the several novel features of construction and arrangement which are fully set forth in this specification and particularly defined in the claims.

The invention is clearly illustrated in the drawings furnished herewith in which- Figure 1 is a side view of a glass cutter embodying my invention, Fig. 2 is an edge view thereof looking in the direction of the arrow 2 in Fig. 1, Fig. 3 is a view partly in side elevation and partly in section, the line of section being indicated at 3-8 in Fig. 2, Fig. 4 is an end view of the device,

- Fig. 5 is a perspective View of a clip, Fig. 6

is a perspective view of a wad of absorbent material used in the tool, Fig. 7 is a-side view of a modified form of the device, Fig. 8 is a cross sectiontaken on the line 88 Fig. 7, Fig. 9 is a view of a second modified form of the device partly in section, Fig. 10 is a view of a third modified form of the device and Fig. 11 is an edge view of the form shown in Fig. 10.

Figs. 1 to 6 inclusive illustrate the preferred form of the tool, and in said views 10, represents the handle of an ordinary glass cutter, which has a head portion ll, extending out from it at one end. The sides of the head are fiat and unprovided with any projections which might contact with the straight edge along which the tool is drawn in cutting a pane of glass. As is customary,notches 12, are formed in one edge of the head to provide tongues 13, for breaking away projecting edges of the severed glass. The cutter wheel or disk is seen at 14., and said wheel or disk is journaled upon a pin 15, secured in the forked end 16, of the head. It is quite important in this class of tools that the wheel have very little play between the two members of the fork, otherwise the wheel is apt to Wabble in cutting the glass, thus producing a poor cut, with the danger that the glass cannot be broken off along the cut. In using a tool of this description, frequent application of oil to the wheel and pin is necessary in order to make perfect cuts, and if the tool is used but a very short time without oiling, the wheel and pin become worn and the tool is useless. To overcome this difliculty I provide a wad of absorbent material 17 as for instance felt, which is attached to the tool in such position as to constantly apply the oil to the wheel and pin. In the preferred form the wad is held in place by means of a clip 18, which is secured to the head by means of a screw, rivet or like fastening 19. As shown, the clip is formed with a top 20, and two sides 21, and the clip is placed upon one edge of the head 11, thereby forming a recess or socket 22. The wad 17, is placed within the clip so as to leave an end 23, projecting slightly beyond the open end of the clip, and preferably in contact with the wheel or disk. The best results are obtained if the wheel or disk is partially embedded in the wad and the latter brought as near the pin 15, as is possible. This arrangement causes the wad to apply the oil directly to the wheel, keeps it well oiled and consequently cool.

In operation the glazier or other person using the tool, dips the end of the tool in a cup or can of oil or other lubricant, the wad absorbing a quantity thereof and becoming thoroughly saturated. The tool may now be used to cut panes of glass, and the wad will apply oil to the wheel and pin until the supply is exhausted. It is quite evident that by reason of the oil saturated wad, oil will be applied to the wheel and pin, regardless of the position in which the tool is held, and it frequently happens that a glazier must necessarily hold the tool in a horizontal position in cutting a pane of glass which happens to be supported in a vertical position. Regardless of this fact, the wheel and pin will be oiled continually by the saturated wad.

In the form shown in Figs. 7 and 8, the clip is made readily removable from the head. This is accomplished by providing one or more ribs 2A, upon the clip that rest in grooves 24, formed in the head. The ribs and grooves should be located well above the cutter wheel so as not to interfere with the straight edge when the tool is drawn along the same in cutting the glass.

Fig. 9 shows a cutter head formed with a lateral projection 25, in which is formed a socket or recess 26, adapted to receive the Wad of absorbent material.

Figs. 10 and 11 show the socket or recess 27 as extending transversely through the head with the wad 17 in engagement with the wheel and projecting down in front of the same. The effect of this is that the wad applies oil to the glass as well as to the wheel and pin, and this is found to be very helpful in cutting glass.

The advantages of this device are readily apparent. The unnecessary time which is often required in cleaning the reservoirs or oil passages of fountain glass cutters is avoided, and the repeated filling thereof is dispensed with. The tool is simply dipped occasionally in lubricating fluid and is ready for use.

I am aware that besides the ones which I have shown and described, various other alterations and modifications of the device are possible and I do not desire therefore to limit myself to the particular forms shown and described.

I claim as new and desire to secure by Letters Patent:

1. As a new article of manufacture, a glass cutter comprising a handle having a cutter wheel ournaled therein and provided with a partially exposed wad of absorbent material contacting with the cutter wheel and arranged to apply oil directly thereto.

2. As a new article of manufacture, a glass cutter having a rotary cutting device journaled in one end, and a partially exposed wad of absorbent material secured in place adjacent to and contacting with the cutting device and adapted to apply oil directly thereto.

3. As a new article of manufacture, a glass cutter, having a rotary cutter wheel journaled therein, a partially exposed oil applicator secured adjacent to and contact ing with the cutter wheel for applying oil directly thereto.

4. As a new article of manufacture, a glass cutter having a rotary cutting wheel journaled therein, a partially exposed wad of absorbent material arranged adjacent to and contacting with the cutter wheel for applying oil directly thereto, and a suitably supported clip for holding said absorbent material in place, said clip partially inclosing the absorbent material.

5. As a new article of manufacture, a glass cutter having a rotary cutter wheel journaled therein, and a suitably supported and partially exposed wad of absorbent material for containing oil and in which the cutter wheel is partially embedded.

(3. As a new article of manufacture, a glass cutter having a rotary cutting wheel journaled in one end, a partially exposed wad of absorbent material in which the wheel is partially embedded, and a. clip secured on the body of the glass cutter and partially inclosing the wad.

7. As a new article of manufacture, a glass cutter having a rotary cutting Wheel journaled in one end, a partially exposed wad of absorbent material in which the wheel is partially embedded and a removable clip secured on the body of the glass cutter and partially inclosing the wad.

8. As a new article of manufacture, a glass cutter having a rotary cutter wheel journaled in one end, a socket adjacent to the wheel and a partially exposed wad of absorbent material seated in said socket and contacting with the cutting wheel and adapted to apply oil directly thereto.

As a new article of manufacture, a. glass cutter having a rotary cutting wheel journaled in one end, a socket adjacent to the wheel and a partially exposed wad of absorbentmaterial seated in said socket and having an end projecting beyond said socket in which the cutting wheel is partially embedded.

10. As an article of manufacture, a glass cutter having a rotary cutting wheel journaled in one end, a three sided clip secured upon one edge of the body of the glass cutter and forming a. socket, and a wad of felt seated in said socket and having a protruding end engaging with the wheel for apply ing Oll thereto.

In witness whereof, I have hereunto subscribed my hand at Chicago, Illinois, this 2nd day of January 1909.
